What did/would/have you use for yours or anyone you know 2001 bow sac??? I just found out theres some funky vent box up there that might mess a little with distributing the wieght of a sac equally side to side so I was hoping to get some input? Ill usually be riding with 3 or 4 guys and gonna be running a 1000 lbs out back so let me know what you used or think!
